Question

I have a BST database that i have to export to a .CSV file. i can get it to export the first record. how can i get it to loop until the entire database is exported.

void ActorBST::ExportToCSV(NodeActor *node)
{
    string fileName;
    cout << "File Name(include .csv): ";
    cin >>fileName;
    ofstream myfile;
    myfile.open (fileName);
    myfile << "Year , Award, Winner, name, film"<< endl;
        myfile << node->year << "," << node->award << "," << node->winner << "," << node->name << "," << node->film<< endl;

    myfile.close();
}

Answer 1

// since you want the entire database , you have to traverse throught the bst , get the data and then export .

void get(NodeActor* node, ofstream myfile)
{
if(node==NULL)
return;
myfile << "Year , Award, Winner, name, film"<< endl;
myfile << node->year << "," << node->award << "," << node->winner << "," << node->name << "," << node->film<< endl;
get(node->left,myfile);
get(node->right,myfile);
}
void ActorBST::ExportToCSV(NodeActor *node)
{
string fileName;
cout << "File Name(include .csv): ";
cin >>fileName;
ofstream myfile;
myfile.open (fileName);
get(node,fileName,myfile);
myfile.close();
}
